Politifact, a fact-checking website from the Tampa Bay Times, is a handy tool when you want to know the real story behind a political soundbite, even when you don’t like the results. Most of the time, the details are a lot more complicated than the sound bite would lead you to believe, and if you click on the quotes and read the entire explanation, you can see how the information was distilled and sometimes twisted. You can guess how the politicians quoted feel about it. Imagine Politifact following you around and checking the validity of the things you say all day. It would only take about five minutes before you are ready to strangle it. This is the latest from Randall Munroe at xkcd. Go to the link to see the hover text punchline.
